Overiding methods from String

[Daniel Martins]

Hello Ranchers

Being String a final class, how is it possible to override a method like toString() ?

class A{
    private int i;
    @Override
     public String toString()
   {
       if(i == 0) return null;
       else return ""+i;
   }

Ok, it just occured to me that if we do not extend String (because we can't), we are basically creating a new method called toString with return type String.

The original one is not visible from within the class...

Am I rigth here...?

It can still be called via "super.toString()", though.

Daniel, a quick reminder is that the toString() method is inherited by all classes from the Object class not the String class. That toString() method is not final and therefore you can override it till the cows come home.

Ok, I made a wrong assumption.

Thank you!
